Transfer your DTag to another user

:::tip Rewards
Upon completing this challenge, you will be rewarded 100 Desmos Tokens.

Please note that in order to prevent spam, you will receive the reward just for the first transfer you perform. No tokens will be awarded for later transfers. :::

With version v0.12.0 we've implemented the ability for users to exchange between them their DTags.

Exchanging your DTag

:::warning Requirements
In order to be able to complete this challenge you will need:

  1. A profile with a DTag properly set.
  2. A friend with which to share your DTag that will need to accept the request or a second profile with a DTag set.

In the following commands examples we will use two local keys, each one with a profile set to it. If you want to do the same, in order to register a new key use the following command:

desmoscli keys add <new-key-name>

:::

Transfer your DTag

Transferring a DTag is a process composed of two different steps:

  1. Preparing for the transfer by executing a transfer-dtag transaction.
  2. Accepting the transferring by performing an accept-dtag-transfer transaction.

So, firstly we need to prepare for the DTag transferring. You can do so by executing the following command:

desmoscli tx profiles transfer-dtag <User address> \
  --from <your-key-name> --yes \
  --chain-id <chain-id>

The <User address> should be the address of the DTag recipient.

Here's an example of such command:

desmoscli tx profiles transfer-dtag $(desmoscli keys show alice -a) \
  --from jack --yes \
  --chain-id morpheus-10000

In this case, we are transferring the DTag from Jack to Alice.

Once you've run that command you will be asked to type the password you've chosen during the setup and after having inserted it properly you should see something like this:

height: 0
txhash: E4920B61BFCFB935124FFC22BC04C1D5619943B138C87913E6EBCF2B5E892290
codespace: ""
code: 0
data: ""
rawlog: '[]'
logs: []
info: ""
gaswanted: 0
gasused: 0
tx: null
timestamp: ""

To make sure the transaction has been processed successfully, you can query it using the following command:

desmoscli query tx <hash> --trust-node --output json

# Example
# desmoscli query tx E4920B61BFCFB935124FFC22BC04C1D5619943B138C87913E6EBCF2B5E892290 \
  --trust-node --output json

This will return you the JSON representation of the transaction itself.

Accepting the transferring

Once that you started the DTag transferring, the receiving user needs to accept it. To do so, they can use the following command:

desmoscli tx profiles accept-dtag-transfer <New DTag> <Sender address> \
  --from <their-key-name> --yes \
  --chain-id <chain-id>

The <New DTag> will be the new DTag that is going to be associated to them once they gave you their current DTag.
The <Sender address> must be the same address of the user that has started the DTag transferring.

Here's an example of such command:

desmoscli tx profiles accept-dtag-transfer \
  "Alice_New" $(desmoscli keys show jack -a) \
  --from alice --yes \
  --chain-id morpheus-10000

As you can see, here the transaction is performed by Alice specifying Jack's address as the sender.

Once you've run that command you will be asked to type the password you've chosen during the setup and after having inserted it properly you should see something like this:

height: 0
txhash: E69770F29145C0035461B263F6F52F1636B9679F138ABF230CEFBDA11F8E28EA
codespace: ""
code: 0
data: ""
rawlog: '[]'
logs: []
info: ""
gaswanted: 0
gasused: 0
tx: null
timestamp: ""

Getting the reward

After you've transferred a DTag, to make sure you receive your reward please follow this procedure:

  1. Create a fork of this repo inside your private GitHub profile.
    If you do not know how to do it, follow the GitHub fork guide.

  2. Pull the fork locally:

    git clone https://github.com/<your-name>/primer.git ~/desmos-primer
cd ~/desmos-primer

  3. Make sure your fork is up to date with the Primer repository:

    git remote add upstream https://github.com/desmos-labs/primer.git
git fetch upstream
git rebase upstream/master

  4. Create a file named after your GitHub username containing the transactions hashes:

    echo "<transfer-tx-hash>" >> ./phase-6/submissions/transfer-dtag/<your-github-name>
echo "<accept-tx-hash>" >> ./phase-6/submissions/transfer-dtag/<your-github-username>

# Example
# echo "E4920B61BFCFB935124FFC22BC04C1D5619943B138C87913E6EBCF2B5E892290" >> ./phase-6/submissions/transfer-dtag/RiccardoM
# echo "E69770F29145C0035461B263F6F52F1636B9679F138ABF230CEFBDA11F8E28EA" >> ./phase-6/submissions/transfer-dtag/RiccardoM

  5. Commit the changes, push them to your forked repo and create a pull request. If you do not know how to create one, refer to the GitHub Pull Requests guide.
